BACKGROUND

Nowadays, many devices depend on USB output to power and recharge theirinternal battery and portable electronics. However, sealed lead acid(“SLA”) batteries are not known for being charged via a Universal SerialBus (“USB”). Traditional USB circuits provide power and data lines tocommunicate to coupling devices, with a single voltage and current. Inthe past, a user needed to connect power packs and jump start systems totheir home electrical outlet or cigarette lighter socket to rechargethese systems. The disclosed novel device overcomes these limitationswith prior charging devices.

SUMMARY OF THE DISCLOSURE

Disclosed generally is a sealed lead acid (SLA) battery jump starterthat charges via a USB. In addition, a power-out feature can be added tothe USB port, which can provide for a 2-way (power in and power out)USB, with the output preferably having a ‘triple voltage select’feature. The novel disclosed triple voltage select feature can allow foran output of either 5V, 12V or 20V, though such values are notconsidered limiting and other voltage values can be used and areconsidered within the scope of the disclosure. Also, having a tripleselect is also not considered limited, and other selects (e.g. doubleselect, four select, etc.) can be chosen and also considered within thescope of the disclosure. To charge the jumper's internal SLA battery,the USB input can be a 5V USB charging system with a boost converter.

The disclosed rechargeable power pack can comprise several features,with most features directed to providing temporary emergency power incase of an emergency such as a power outage, dead vehicle electricalsystem, and/or recharging a low battery for an electronic device.

Additional non-limiting features can include providing power to rechargesmall consumer electronic devices such as, without limitation, cellphones, iPad, tablets, note pads and others.

The disclosed device provides for higher power, a versatile design, andhigher efficiency by integrating a USB charging circuit to recharge alead acid battery in conjunction with drawing power from the lead acidbattery to provide a preferred triple output switch mode selectablepower. The disclosed device provides for a USB rechargeable chargingcircuit that can be capable of providing INPUT low power to rechargelead acid batteries and also provide POWER OUT (preferably) TRIPLEVOLTAGE AND CURRENT to recharge high output electronics.

The USB charging INPUT can be preferably compatible to charge large leadacid batteries as large as a full vehicle battery and as small as alawnmower type of battery. The POWER OUT can recharge high outputelectronics using the disclosed (preferably) triple output switch modeselect option. One non-example of a high output electronic that can becharged with the POWER OUT capabilities of the disclosed device is alaptop demanding 20V and 5A of power to recharge.

In onenon-limiting embodiment, the USB IN can recharge a lead acid batterysuch as at a low rate of 12V, and the USB OUT can be triple voltageselectable 5V, 12V, 20V with its corresponding current, with the USB INand USB OUT features preferably all integrated in the same system. Withthe disclosed novel device, a sealed lead acid battery for a jumper canbe charged via a USB.

In one embodiment, a micro USB input port can be used, while in anotherembodiment a two-way USB port (such as those previously patented by theInventor and incorporated by reference herein in their entirety) can beused. A voltage booster inside the jumper can be provided to allow the5V 2A USB port of the adapter or any other 2A USB adapter (e.g. iPad) toup convert to 12V and have enough power to fully charge the 12V battery.This “up” converting allows for converting the inputted 5V up to 12V.The preferred 12V value is preferred and not considered limiting andother voltage values can be used and selected and are considered withinthe scope of the disclosure.

It is also within the scope of the disclosure to incorporate orintegrate USB-C technology to allow for more power to be used, which canallow for increased/faster charging times.

Thus, the disclosed circuit allows recharging large batteries in powerpacks via a relatively low power USB. The power packs and/with jumpstart system can be provided with multiple output capabilities via USB.The multiple output capabilities and recharging capabilities through theUSB port can be all integrated in a single system.

The disclosed novel device can be used to provide portable power in caseof an emergency such as power outage, dead vehicle electrical systembattery, etc., while also be able to provide power to recharge smallconsumer electronic devices such as cell phones, iPad, tablets, notepads, etc.
